ARM: dts: msm: reduce APC0 SVS and NOM CPR margin by 25 mV for msm8994 



Specify conditional CPR target quotient and initial voltage adjustment
values for VDD_APC0 Revision 3 and 4 cpr-regulator devices on MSM8994.
These adjustments remove excess voltage margin from the target values used
by the APC0 CPR controller. This in turn reduces system power consumption.
